x4 hull 800 skat trak pump problem

hi i would like to inquire about this issue.water is not flowing into my engine,i checked all the water lines and made sure that there are no debris.im suspecting the pump does not pump water into the lines going to the engine and will cause overheating.is this a pump issue?its a 6 vane skat trak pump.the clearance into the wear ring is ok and there is enough thrust coming from the pump.but no water going to the engine.

before installing everything since it over heated,i run some compressed air in all the lines,but what im gonna do tom is to pull out the water line from the head and run compressed air if i can feel the air coming out from the pump then its not clogged..this is my 1st time with this kind of problem.
